1) Oh, that's nice. Personally it's not that odd to me, since I'm used to "wolf" being used poetically to represent predators or aggressors. If it's there early, I'm sure people will just take it in as how this world works.
2) That makes sense, I understand now. For Head Doctor, it's embryo-like enough to be unclear if it's actually a human, so it isn't that much of an outlier. Maybe some edits to make it a bit more of an animal embryo and you can call it a day. Since it's the second enemy in the game, or possibly third if the player found Premature, it's probably better for all three to be in-theme to already transmit the idea of what you're fighting with in the game.
3) Recruitable Mothman real?
Also, thank you for your time
